Mocha Chocolate Chip Espresso Cupcakes

Mocha Chip Espresso Cupcakes

Have I mentioned how much I love my Bouchon Bakery cookbook? I got it for my birthday back in February, and even though I’ve spent hours staring at the lovely photographs (it’s my new coffee table book), I’ve hardly made any of the recipes. I’ve been dying to try the devil’s food cake, since it’s one of my very favorite desserts ever, so I was really excited to try Thomas Keller’s version. You might remember the devil’s food cake I made for my birthday this year, which I absolutely loved, so I wanted to see how this would compare.

The recipe differs quite a bit from the Baking Illustrated version. There’s no melted chocolate, and mayonnaise is used instead of milk or sour cream. I know what you’re thinking. Mayonnaise? In a fancy French cookbook? I thought the same thing. Chocolate mayonnaise cake was popular in during World War 2, when certain ingredients were in short supply and people had to get creative. If you think about it, it makes sense. Mayo is made of egg, oil, and vinegar, which are all common ingredients in cakes anyway.

I hate to use the word moist, because it makes me cringe a little bit, but for lack of a better word, this cake was moist. The moistest chocolate cake I have ever made. Like with any cake, I highly recommend using a kitchen scale to make this. Not only is it more accurate, but it creates less dishes. :)

I normally use real or instant espresso in my espresso frosting, but this time, I tried coffee extract. I have to say, I liked it better. It gave a strong coffee flavor without being too bitter. Plus, I didn’t have to wait for the espresso to cool or the espresso powder to dissolve. I also added a few teaspoons of coffee extract to the cupcakes to give them a mocha flavor. Of course, you can sub either of these ingredients for coffee extract if you don’t have any on hand.

The original recipe calls for a 9-inch cake, but I wanted to try it in cupcake form. I managed to squeeze out 12 cupcakes by getting every last ounce of batter out of the mixer, but next time, I’ll probably make 11 so each one will be a little bit bigger.

  11. These sound to die for, but I don’t understand the 3 1/2 TBSP of egg. Please clarify.


    1. 56 grams is approximately one large egg, but if you don’t have a scale, you can beat the egg and measure it out in tablespoons.

  13. Is there a way to substitute espresso powder for the coffee extract? Would love to make these with the coffee flavor but don’t want to wait to order the extract. Thanks!

    1. Yes, absolutely! You can dissolve 1 tablespoon on instant espresso powder in one teaspoon of boiling water. Make sure that it has cooled to room temperature before mixing it into the frosting.
